Application led April 21, 1916. `Serial No. 92,810.

To all whom t may concern:

Be it known that we, AUGUST H. YOUNG and JAMES S. YOUNG, citizens of the United States, and residents of Jersey City, in the county of Hudson and State of lNew Jersey, have invented certain new and useful lm-l provements in Sand-Distributing Devices, of which the following is a specification.

This invention relates to a sand distributing device for automobiles or the like to prevent skidding. invention comprises essentially a set of sand boxes having u series of spouts extending therefrom. The sand is e]ected from the spouts by compressed nir und strikes a concave shield which distributes the sand over a Wide area in front of the rear wheels of the vehicle. The compressed air and the sund ej'ecting menus are -under control of the operator of the vehicle, at his seat.

In the accompanying ldrawings Figure 1 represents a top plan view of the invention connected to an automobile; and Fig. 2 shows an elevation of Fig. 1 and partial section as on the line 2, 2 of Fig. 1.

The automobile is represented with the| members 20. 21 of its frame which support the body 22, with the Hoor 23. The main driving shaft of the automobile is indicated at 25, and has connected thereto 'the split inion 26. A clutch shaft 30 is Journal 1n the journal brackets 31 and 32, which are fastened to the member 20 of the frame of the vehicle. The female member 35. of a` friction clutch is journaled on the shaft 30 on the periphery there- The male member 38 of the friction clutch is supported on the shaft 30 and is slirlable on a spline 39 of the said shaft. A spring 40 encircles the shaft 30 and bears between the outer end 'tace of the member 38 and the accompanying face of the bracket 32. A disk 44 is fastened to the shaft 30 and carries a pin 45. An air compressor 46 is supported from the member 20, anda the 1ston rod 47 of the compressor 1s plnne to one end of the connecting rod 50. The other end of the said connecting rod 50 is suported on the pin 45.

rom tile member 20 the bell crunk The upper end ter is pinned to the male member clutch, and the lower end of the bell crunk is pinned to one end of the connecting rod A controlling cylinder is indicated at A.' It contains a piston-61 from which exand has pinned thereto The organization of the the A bracket extends sthe sund boxes 7l und 72. of the lat-w 38 of the tends the piston rod 62. The latter is pinned to the al]acent end of the connecting'rod 58. An' air reservoir 64 with a. safety valve 65 is located in the rear portion of the vehicle. Piping 66 with thecheck valve 67 connects the compressor 46 and the reservoir 65. Pip mg 68 connects the controlling cylinder 60 and the said reservoir. Brackets 70 extend from the members 20 and 21 of the frame of the vehicle and support the simil-1r sand boxes 71 and 72. Removable screw plugs 7 3 are provided for each of said sand boxes. Each sand box has provided therefor ra sand outlet nozzle 75 with three spouts 76, 77 and 7 8. A sand outlet valve 80 1s interposed be. tween each nozzle 7 5 and its-accompanying sand box. A cross-shaft 83 is journaled in ournal boxes 84 extending from the memrs v20 and 21. The shaft 83 has extending ltherefrom thel normally horizontal arms 85, and the latter' are connected to the valve spmdles 86 of the valves 80 by means of the links 88. Normally vertical arms 92 extend from' the cross-shaft 83. Air inlet valves 93 are provided for the sand boxes 71 and 72.. Links 94 connect the spindles of the latter valves and the arms 92. A normall vertical arm 95 extends from the cross-sha t 83 and has connected thereto one end of the reach rod 96. The other end of the rod 96 is pinned to the sector arm 97, which can be pignned in dilerent positions of the sector 65 and branch piping pipe 100 an t 101, and 102 connects 93 and leads into the sand boxes 71 and 72. A perforated connected to the piping 105. Conca'ved shields 110 extend from each side of the running board (not shown) little below the spouts 77l to 78.

VTo operate the invention the operator moves the sector arm 97 in the direction of the arrow A, by which the valve spindles 86 of the valves 80 and the vvulves 93 aremoved to open said valves simultmumusl y. The, opening of the valves S0 enables the discharge of the sand from The san is forced out of the sund boxes by reason of the nir pressure exerted upon tbc top ofthe sund by thc olsning of the valves 93. The nir is discharged into. the sund boxes through the erforntions of the coils 106.

Piping 100 extends from the reservoir.

spindles of the Y l e air inlet valves 93. Piping 105 extends from each of the valves and project t0 91,'

lio

To maint-.un the rcquisitcprcssurc in the .the bell crank 55 and its connections with the piston 61, the membersof the clutch are disengaged from each other and the female member ofv the friction clutch turns on the shaft 30.

The s outs 77 to 78 with the coaction of the shie d 110 distribute the sand on a wide area on the surface of the ground in front of the rear wheels of the vehicle, which 'prevents the Wheels skidding.

Having described our invention what We desire to secure by Letters Patent and claim 1s:

1'. In an apparatus of the character described 'the combination, of a sand box, a'n outlet nozzle for the sandbox, means to *force air under pressure into said box'to discharge sand or `the like therefrom and a shield in front ofthe nozzle.

2. In a vehicle ofthe character described the combination, of a Ina-in driving shaft,

. an'- air 'compress6r, for the vehicle, an air reservoir `to store compressed air produced by said compressor, driving 'mechanism for' said compressor controlled by the pressure of the air 1n 'said reservoir, a sand box for vspouts, an air inlet valve for each sand box,

an air reservoir -or the apparatus, piping `between the reservoir 'and each air inlet vulve and means to operate all the" valves simultaneously, and with the opening of the valves forcin con'ipressed air into the sand boxes and ischarging sand. or the like therefrom on the path of the Wheels of said vehicle.

LL. In an apparatus of the character described the combination of a pair of sand boxes, a perforated coil in each sand box, an outlet nozzle for each sand box, a shield opposite each nozzle, an air inlet vaive for each sand box, means to conduct compressed air to each inlet valve and thence through the perforated coil coacting therewith and means to operate the val fes simultaneously'.

Signed, at Jersey City in the county of Hudson and State of New Jersey this 15th day of April A. D. 1l i6.
